When I was doing graphics design for one company, I had to do these. It was because of him that I made this decision, on the norms I don't do this. The fact that I was not the only staff doing graphics there made my decisions stand firm as my boss said he could meet another colleague of mine for his work.
His character sucks, he will be like do this, do that, man your not competent, my friend I want this to be like this on the process of making it the way he wanted, boooom he changed his mind don't do it that way again, do it this way, sorry change this I made a mistake says he. After the whole stress he will say start again I don't accept this. But you were sitting right close to me instructing on your satisfaction, now your saying start afresh. Like I told you guys his charact sucks.
Next time he came, I took it easy on him by just saying Sorry, I can't work for you, for me I don't rant with customer as not to make him feel as am chasing him away.
